Sandy, I have tried printing digital negatives on Pictorico OHP and I can easily see a "texture" to the negative that is not there on paper or the white film. This carries over to the print when using silver gelatine prints. I have also seen some of Jorge's platinum prints and I beleive that the texture would also be visible in these. Do you see the "texture", for lack of a better word, in your negatives made on OHP with the 2200? I would love to make platinum prints as fine as Jorge's but I doubt it will work with OHP - am I wrong?

I have made fine digital negatives with the pictorico white film for silver printing.
